BOTTLE-SEALING MACHINE.

To all whom 'it may concern:

Be it known that I, ALFRED L. WnIssEN- THANNER, a citizen of theRepublic of France,

and a resident of New York city, State of New York; have invented acertain new and useful Improvement in Bottle-Sealing Ma-. chines, ofwhich the following is a specification.

My invention relates to a machine for capping bottles and similarreceptacles having an annular shoulder or bead around the head, theobject being to construct a machine which shall comprise as an essentialfeature a chuck or die into which the bottle is forced in such manner asto reshape the cap to conform to the contour of the rim of the bottle,and in which provision is made for all inaccuracies or irregularities inthe form and size of caps and bottlesliable to be met with in practice.This chuck in the form shown in the drawing is held rigidly againstvertical movement, although it may be vertically movable, and is splitlongitudinal] to form a series of spring jaws which will a1 ow of aslight'radial yielding movement when a bottle is forced into it, thussecuring a uniform and evenly distrib-' uted pressure upon the corner ofthe cap.

A further feature of the invention com-' prises a crimping or bendingtool which operates to circumferentially bend the flange of the cap intolocking engagement with the shoulder of the bottle, said tool being aranged relatively to the chuck and its oper tion being so timed as toeffect the desire crimping or bending after the cap has been reshapedand while the bottle is held fast between the table and the chuck.

Another feature ofthe invention comprises means for concavin the centerof the cap'..

The invention wi I be understood by reference to the accompanyingdrawings in which Figure 1 is a side elevation of a bottle sealingmachine embodying my invention in its preferred form; Fig. 2 is a frontelevation with certain of the parts in section; Fig. 3 is a top planview; Fig. 4 is a detail view of the head of the machine with the framein section; Fig. 5 is an inverted plan-view of the head; Fig. 6 is avertical section. of the head showing the means for closing the crimpingtool about the neck of the bottle; Fig. 7 is a top plan view of the headof the machine; Fig. 8 is a sectional view on the plane of the line 88of Fig. 6 lookin in the direction of the arrow; Fig. 9 is a detai viewshowing the bottle neck and chuck in position before sealing; Fig. 10

Referring to the drawings the numeral 1 form of a casting whichisprovided at its lower art with a bearing for a shaft 2 which shaft 1salso supported in a bearing in a standard 3. Pivotally su ported on ashaft the rear end of which, when depressed, is adapted to strikeagainst the under side of an arm 6 secured to a rock shaft 7. On thisrock shaft is an arm 8 (Figs. 1 and 3) the upper end of which isU-shaped and engages a collar 9 on a clutch 9' slidably keyed on shaft2. This clutch, when the treadle is deressed, is, moved so as to bringpulley 11 into 0 erative engagement with the shaft 2 Where y the latteris rotated from the power shaft by a belt passing around the pulley 11.Supported in bearings'in the frame 1 is a shaft 12 on which is pivotallymounted a le- 'ver 13 the forward end of which is forked supported intubular extensions 15 of the ame 1-. Passing longitudinally through aidsleeve is a s indle 16 which is surrounded by the forke ends of lever 13but not in engagement therewith. The spindle 16 carries at its upper enda table 17 adapted to receive the bottle to be capped, and said tablemay be provided with a gage- 18 for the proper centering of the bottle.Clamped to and the lower wall of the sleeve 14, and surrounding thespindle 16, is a spring 20 which acts as a cushion when the bottle isforced upward a ainst the chuck.

Integra with the treadle 4 is an upwardly projecting arm 21, which, whenthe treadle ing om lever 13 therebly rocking said lever and elevatingits forwar end and raising the sleeve 14, and through the s ring 20 alsoraising the spindle 16 so as to ring the bottle with relation to thechuck to about the osition shown in Fi 9. The rear end of ever 13supports a rol er 23 which is adapted to be acted upon by a cam 24 faston the designates the frame of the machine in the,

5 in the lower part of. the rame is a treadle 4,

(Fig. 2) and upon which rests a sleeve 14' spindle 16 is a split collar19 between which 1s dapressed, acts against an arm 22 depend Fig. 12 isa decam 24 a short distance butnot far enough i to escape the ath ofsaid am.

I shown in Fig. 9,. the cam 24 then acting upon "and the bending tool.

said spindle by a collar 31 which is forced be- .a chuck and will be soreferred to. the bottle is forced upward these working bythe jaws 33 issubstantially equal to the shaft 2. When the treadle4 is depressed, theroller 23 is moved away from the face of As stated a ove the depressionof tre'adle 4 raises the bottle into about the position roller 23 willdeliver a sudden blow so as to cause the lever 13 to further raise thesleeve 14 and to forcibly project the bottle against the chuck. As cam24 wipes from off the roller 23, the weight of sleeve 14 is sufficientto rock lever 13 so as to bringv the roller 23 into contact with theface of cam 24, and to rock the treadle 4 through the arms, 22 and 21 torestore it to its normal position. A s ring 25 secured to the arm 6 willmove the c utch in a reverse direction so as to release the pulley 11and the machine will come to a position of rest.

Formed integral with the frame 1 is a head 26 bored longitudinally inalinement with the spindle 16 and adapted to support the chuck The head26 is formed with four inwardly projecting lugs 27 which permit of thefree passage between them of a spindle 28. To the under side of the lug;27 are bolted brackets 29 ,which are formed integral with a steel ring30 which surrounds the spindle 28 said ring being clamped about tweensaid ring and the inner walls of the lugs 27. The spindle 28 isscrew-threaded for a portion of its length to receive a jam nut 32 whichis forced up against the lower end of the. ring 30. The ring 30 is alsoscrewthreadedand adapted to engage the threaded portion of the spindle28 so that said spindle may be adjusted vertically although held rigidlyagainst vertical movement when once a justed. The lower end of the sindle 28 is reamed out to form a sleeve 33. he spindle is of steel andsaid sleeve is split longitudinally to provide a plurality of radiallyyielding spring jaws 33 having at the inner sides of their lower endssuitable concaved working faces. The sleeve 33 constitutes in efi'ectWhen faces. receive the corner of the cap.

The inner diameter of the chuck formed diameter of the rim of thesmallest bottle liable to be met with in practice within the range ofprobable variations of size and she e. The function of the chuck is thatof t e female member of a die so that under the pressure applied to thebottle acting as a punch a uniform and evenly distributed pressure willbe applied about the corner of the cap to reshape it and to cause it toconformexactly to the rim ofthe bottle.

The present machine is designed not onlv frame.

to reshape the cap of the bottle but to bend the flange of the cap intosecure locking eni gagement with theshoulder on the neck of the bottle.The mechanism for accomplishthe latter object of the invention is as i If dTlows:Having a loose bearing on a stationary shaft (see Fig. 1) is alever 34 one arm of which carries a roller 35 held in con tact with theface of a cam 36, fast on the shaft 2, by a spring. 37 secured to theother arm of'said lever and to a fixed stud on the The other arm oflever 34 is secured to one end of a vertical rod 38 the upper end ofsaid rod being pivotally hung to a stirrup 39 encircling and secured toa lever 40, said lever 40 being pivoted on a shaft 41 having hearings inthe frame. The forward end of lever 40 is forked (Figs. 1 and 3), and inslots 41 formed in the projecting arms are supported lugs 42 integralwith a sleeve 43. The spindle 28 projects into said sleeve in thevertical movements of the latter. The lower end of sleeve 43- is formedwith a cam face 44 adapted to operate a sectional flange bending toolwhich is constituted of a series of jaws 45 each having an inwardlyprojecting shoulder 46 made with a more or less sharp crimping edge 47-These jaws 45 are struck on the arc of a circle and when assembledconstitutea bending tool adapted to bend the flange of a sealing capinto locking engagement with a shoulder on the bottle head.- Each jaw isformed with a shoulder on its inner upper wall adapted to engage acollar 48 secured to the spindle 28, the latter beingcentrally disposedwithin the bending tool. To the outer side of each jaw 45 is secured, bymeans ofa screw bolt, the lower end of a spring. arm 49, said springsbeing bowed outwardly (Figs. 4 and6) and tightly clamped at their upperends between the ring30 and collar 31 (Fig. 6). The normal positions ofthe jaws 45 is such as to leave a space between contiguous edges so asto permit their lower ends to be moved inwardly to form a practicallyclosed circle about the neck of the bottle when pressure is applied tothe sides of the spring arms 49. The crimping edge 47 may be smooth orknurled, and a greater or less number of jaws than that shown in thedrawings may be arran ed. This closing in of the jaws of the bendingtool is effected by cam 44 through levers 5O pivoted on studs 51 securedto the contiguous walls of brackets 29 (Figs. 4 and 8). The levers 50carry at their upper endsrollers 52 and at their lower ends are formedwith threaded eyes 53 to receive adjustable bolts 54 which bolts'projectinto close proximity to the bowed sides (if-spring arms 49. These partsare so adjusted that as the sleeve 43-is moved downward onthe spindle 28the cam 44 will contact with rollers 52 thereby rocking levers 50 andforcing the bolts 54 against the spring arms 49 to close the jaws 45 ofthe bending tool about the neck of the bottle.

The operation of the machine will be readily understood from theforegoing descrip- ,tion. The cams 24 and 36 are so disposed on theshaft 2 relative to eachother that the former acts u on lever 13 toforce the bottle tially the position shown in Fig. 9-. Such movement ofthe treadle also moves the roller 23 away from, but not out of the pathof, cam 24 so that as said cam is rotated a sharp blow will be deliveredagainst roller 23 to impart a further vertical movementto sleeve 14,thereby forcibly im inging the to of the bottle against the chuc theplane 0 impact extendin over the corner of the cap 55. I The internaldiameter of the face of the chuck and its configuration are such,relatively to a standard shape and size of bottle and cap, as to effecta reshaping. of the cap into exact conformity with the rim of thebottle. The sealing disk 56' on .the under side of the cap is compressedover the rim and the metal of the crown of the ca formed into a slightlyconvexed form. e spring 20 inclosed within sleeve 14 takes the force ofthe impact of the bottle a ainst the chuck and prevents breakage. Athough the chuck is held rigid against vertical movement the capabilityof radial expansion of the jaws 33 of the chuck, provides for allvariations from a standard shape and size thereby securing uniformity ofpressure circumferentially around the corner of the cap.

the cap, the-cam 36 acts. to raise the outer end of lever 34 therebydepressing lever 40 and bringing the cam face 44 down-against therollers 52 and rocking levers 50 on their pivots. The inward movement ofthe bolts 54 against spring arms 49 effects a closing-in movement of thejaws 45 against the flange 57 of the ca the crimping edge 47 formed bythe severa shoulders 46 being practically continuous around the bottleneck. The u ward movement of the bottle brings t e shoulder 58 in suchposition that the inward movement of the jaws 45 will cause the edge 47to bend the flange of the cap into secure locking e agement with saidshoulder as indicated in ig. 10. Owing to the manner of SIxJSPOItlIIgthe jaws 45 they are capable not 0 y of a radial movement but also avertical displacement downward due to the flexing of the spring arms 49,so that notwithstanding irregularities in the size and shape of thebottle shoulders and caps the edge 47 will always be brought into aposition to eflect the bending of the cap flange 57 under the shoulder.Thus if the height of the shoulder should be greater than the normal orstandard the edge 47 will strike the shoulder at After cam 24 has thusacted to effect the compression and reshaping of.

"some point between its middle and lower circumferential lines and thejaws 45 will accommodate themselves to such variation by sliding overthe curved under side of the shoulder so as to bend the flange into proer locking engagement with the shoulder. he length of levers 50 is soroportioned that the bolts-54 strike a little a ove the center of thebowed portions of spring arms 49 to permit "of this slight downwardmovement of the jaws 45. and to effect the'desired inward radialmovement of said jaws.

It will be understood that the extent of the movements of the jaws 45 isvery small, bein merely sufiicie'nt to effect the desired ben ing of thecap'flange into intimate looking engagement with the shoulder.

When the high point of cam 36 wipes from underroller 35, spring 37 actsto raise cam 44 through rod 38 thereby releasing the spring arms 49 andpermitting the jaws 45 to resume their normal positions. During the criming operation the cam 24 maintains the bott e pressed against the chuckand as soon as thecrimping is completed said cam wipes from OH theroller 23 thus permitting the sleeve 14 to fall, said sleeve in itsdescent rocking the lever 13 until the arm 22 im pinges against t-hearm21 of the treadle 4, the latter-being held in its depressed position bya suitable stop. The bottle then being free may be removed from themachine.

The yielding characteristic of the jaws of both. the chuck and thebending tool permits them to give sufficiently and to prevent thebreakin or crushing of the bottle, and to accommo ate variable sizes andshapes of hottles and caps.

In Figs. 11 and 12 I have shown a modification or addition to themachine. In this modification the spindle 28 is bored lon itudinallythroughout its length but fixed y supported against vertical movement asdescribed heretofore. The sleeve 43 which carries cam 44 is open at thetop, and throu h said opening and passing 'ongitudinal y through spindle28 to near the face of the chuck 33 1s a plunger 59, said plunger beingsupported by a spring 60-surrounding its head and bearing against thetop of sleeve 43 and a nut 61 carried by theplun er. Pivotally supportedon the shaft 41 1s a 'or- Wardly' projecting 'arm 62 the'outer end ofwhich is rovided wit-h a hammer head 63 suspende above the plunger 59and adapted to deliver a blow thereto when lever 40 is depressed by cam36. Near one end of lever 40 is secured ashoe 64 adapted to engage theunder side of a lug 65 projecting from a late 66 whichdplate issupported u on screw olts 67 tappe into arm 62. the lever 40 is in itsraised osition thus suporting arm 62 in a position to deliver its low.When lever 40 is depressed the shoe 64 is-moved from under lug 65 andthrough the spring connection 68, arm 62 is moved downward and a blowdelivered by hammer 63 to plunger 59, the parts being so proportionedthat the plunger will strike the crown of the cap at or lmmedi'atelyafter the time of 0 eration of the bending tool by cam 44.. The lowerend of plunger 59 is conveXed as shown and the diameter of the strikingface is such'as to concave the crown of the cap as shown in Fig. 12,thus effecting a thoroughly eflicient seal. An adjustable stop 69secured to a lug on arm 62 limits the downward movement of arm 62 sothat shoe 64 on its return movement will be held in a position tosustain arm 62. The plate 66 may be slotted as shown in the drawing soas to adjust the position of lug 65 relative to said shoe.
